Radial Pressure Pulse and Heart Rate Variability in Heat- and Cold-Stressed Humans

Figure 2

Pulse measurement and analysis. The pulse was measured (a) on the right radial artery with the subject in the supine position to obtain, (b) a typical radial pressure pulse waveform, and the electrical pulse signal was digitized and analyzed to acquire the corresponding spectrogram, (c) the  Hz band, and (d) the  Hz band.
